As a Google fan boy, this pains me to say this. I had to turn it off :( After everyone connected their twitter, blog, google reader feeds it became the same useless jargon as everywhere else. I'll come back around to it after they change things up.
None really. Problem is that some are close friends who I love having discussions with online and wanted Google Buzz to be that forum style of discussion with friends. Becomes difficult when I see everything else they do already a 2nd, 3rd or 4th time.
That's seems to be a strange stance to take. "Everyone" wants to turn on those features, except for you. And you expect them to turn off those features? heh
